Trafo Power Solutions now offers modular substations
Modular substations, or E-houses, are designed to provide a centralised and secure environment for critical electrical components and infrastructure. These are often used in industrial settings, power plants, mining operations, oil and gas facilities, and other applications, where reliable and efficient electrical power is essential. An E-house can house a variety of electrical equipment such as switchgear, transformers, motor control centres, distribution panels, and other power distribution and control devices.
There is a growing demand for modular substations in South Africa and Trafo Power Solutions has broadened its offerings to include the prefabricated or modular structures that house electrical equipment and systems.
“Dry-type transformers are perfectly suited to the philosophy of modular substations, as they can be safely accommodated inside the compact structure enhancing the benefits that modularity brings,” says Trafo Power Solutions MD David Claassen. “The attraction of the modular structure is that it can be more easily transported and installed on site – and having a built-in transformer just makes sense.”
He explains that traditional oil-cooled transformers must be installed in a purpose-built structure for safety reasons, as there is a risk of leakage, fire or explosion. This often means extra civil engineering construction on site, adding time and resources to the project. The cabling arrangement between the external transformer bay and the substation must then also be accommodated.
“The inherent safety of the dry-type transformer allows it to be installed close to the switchgear inside the modular substation, so there are shorter cable runs and easier installation,” he adds. “The extra cost and management of on-site civils work are also avoided this way.”
Claassen asserts that Trafo Power Solutions now provides a packaged and integrated solution that can meet customers’ requirements for a reliable supply partner with the competence and experience to understand the specific demands of each project and application.
